Abstract

Allenoates are versatile synthetic building blocks, yet their photocatalytic transformations remain underexplored and mostly rely on precious metal catalysts. Herein, we report a mild, noble-metal-free photocatalytic system using 4CzIPN as the photocatalyst, enabling efficient visible-light-driven addition of allenoates with Het/Ar-substituted tertiary amines. This protocol features broad substrate scope and high atom economy. Moreover, it clarifies the reaction selectivity mechanism, opening a new avenue for selective allenoate functionalization.

无金属、可见光活化4CzIPN对氨基烷基自由基向烯丙酸盐加成。

烯丙酸酯是一种多功能的合成材料，但其光催化转化仍未得到充分探索，主要依赖于贵金属催化剂。在此，我们报道了一种温和的，不含贵金属的光催化体系，使用4CzIPN作为光催化剂，使Het/ ar取代的叔胺在可见光驱动下高效地添加了烯丙酸盐。该协议具有衬底范围广、原子经济性高等特点。进一步阐明了反应的选择性机理，为选择性烯丙酸官能化开辟了新的途径。
